LU-1030 osc: new IO engine implementation

New IO engine to manage dirty pages with osc_extent.

Osc_extent is a data structure to manage a series of contiguous
blocks; however, the pages in an extent is not required to be
contiguous. An extent must be written out in one RPC.

The purpose of introducing extents are:
1. make grants work for extent-based OSD;
2. form better IO by picking up contiguous pages to compose RPC;
3. reimplement ll_writepages() with CIT_FSYNC.

LU-56 lnet: allow to create EQ with zero eq_size

Current LNet doesn't allow to create EQ with zero eq_size, it's
an unnecessary limit if the EQ has callback, because EQ callback
is guaranteed to get every event. EQ with no-zero eq_size is only
useful for LNetEQPoll, there is no Lustre use-case that is using
both EQ callback and LNetEQPoll on a same EQ.

Also, even with upcoming LNet SMP improvements, there has to be
a lock to protect enqueue/dequeue operations of event, which might
hurt performance because of lock contention.

This patch will allow user to create EQ with eq_size being zero,
which means events will only be delivered by callback and user
will get nothing by calling LNetEQPoll.

In multiple thread environment, we would suggest user to create EQ
only with callback (eq_size=0) if the EQ might get high rate events,
LNetEQPoll can still work fine if eq_size is non-zero and nothing
will be changed at all. User is still able to create EQ with both
callback and non-zero eq_size, and call LNetEQPoll to get event,
although it's deprecated.

Summary: still can support all current use-cases, although set
eq_size to zero and only rely on callback will be the better way.

LU-1402 libcfs: CFS_ALLOC_HIGH is __GFP_HIGHMEM

According to the comment above CFS_ALLOC_HIGH, the flag
allows allocator to return memory in the highmen zone, but
cfs_alloc_flags_to_gfp() incorrectly converts it to
__GFP_HIGH, which enables the use of emergency pools.

__GFP_HIGHMEM should be used instead. Also it makes sense to rename
CFS_ALLOC_HIGH to CFS_ALLOC_HIGHMEM to avoid further confusion.

* in cl_lock_hold_release(), only CLS_CACHED mode lock will be cached,

from userspace.

CPT table is a set of CPTs:
- A CPT table can contain 1-N CPU partitions
- CPUs in one CPT shouldn’t overlap with CPUs in CPTs of the same
CPT table
- A CPT table can cover all CPUs in the system, or a subset of system
CPUs.

LU-506 dcache: check lookup_instantiate_filp() return value

For new kernels, nd->intent.open.file may not be checked before use,
but it may be an error code. To avoid this, return error when
the original open in lookup_instantiate_filp() fails.
